"The Maximite is a small and versatile computer running a full featured BASIC interpreter with 128K of working memory. It will work with a standard VGA monitor and PC compatible keyboard and because the Maximite has its own built in SD memory card and BASIC language you need nothing more to start writing and running BASIC programs. The design is free and open source including the software and BASIC interpreter."[1][2][3] The "haiqu" has ported BSD to the Maximite and UBW32.[4] Apparently (?) also supports Arduino shields.

"Special Computing" has a list of SBCs and accessories -- BeagleBoard, IGEPv2, HawkBoard, etc. -- Can any of them run Linux?

Many of the other open circuits projects are designed to plug into a standard desktop or laptop PC.

"Building my Own Laptop": "all the design documentation is open, so others of sufficient skill and resources can also build it. The hardware and its sub-components are picked so as to make this the most practically open hardware laptop I could create using state of the art technology. You can download, without NDA, the datasheets for all the components, and key peripheral options are available so it’s possible to build a complete firmware from source with no opaque blobs."

"Funnily enough, the creation of a 15.6in eco-conscious Libre Laptop is exactly what I have been working on for just over a year, now.
The keyboard is implemented using an STM32F072 with 8×16 matrix scanning.
the processor, memory and storage is on a separate removable module, a standard created specifically for the purpose, known as EOMA68.
There are two CPU Cards in active development: one is EOMA68-A20, the other is EOMA68-jz4775.
The first is a dual-core 1.2ghz ARM Cortex A7 (the A20 from Allwinner), the second is entirely FSF-Endorseable: an Ingenic 1.2ghz MIPS processor called the jz4775.
The source code for the casework is GPLv2 and is available *right now* for anyone to 3D-print their own laptop case or adopt it for any other project.
The source code for the STM32F072 firmware is GPLv2, uses libopencm3, and is again available *right now*.
